Claims16
Method of reducing adhesion of microorganisms and reducing development of biofilms on a surface comprising applying to the surface a copolymer of ethylenically unsaturated monomers, wherein the monomers used in forming the copolymerized ethylenically unsaturated copolymers are chosen from:
- 5-95 wt. % of at least one anionic vinyl monomer (A);
- 0-50 wt. % of at least one vinyl monomer (B) containing a secondary or tertiary amino group or a quaternary ammonium group;
- 5-95 wt. % of at least one non-ionic hydrophilic vinyl monomer (C);
- and/or
- 0-15 wt. % of at least one polyfunctional vinyl monomer (F);
- as well as
- 0-30 wt. % of at least one hydrophobic vinyl monomer (D);
- and
- 0-20 wt. % of at least one vinyl monomer (E) comprising silicone groups;
- wherein the sum of monomers (A), (B), (C), (D), (E) and (F) is 100 wt. %.
Copolymers obtained by copolymerization of ethylenically unsaturated monomers chosen from:
- 65-95 wt. % of at least one anionic vinyl monomer (A);
- 0-5 wt. %, of at least one vinyl monomer (B) having a secondary or tertiary amino group or a quaternary ammonium group;
- 5 to 25 wt. % of at least one non-ionic hydrophilic vinyl monomer (C);
- 0 to 2 wt. % of at least one polyfunctional vinyl monomer (F);
- 0-2 wt. % of at least one hydrophobic vinyl monomer (D);
- and
- 0-2 wt. % of at least one vinyl monomer (E) comprising at least one silicone group;
- wherein the sum of monomers (A) and (C) is 80 wt. % or greater, and the sum of monomers (A), (B), (C), (D), (E) and (F) is 100 wt. %.
Copolymers obtained by copolymerization of ethylenically unsaturated monomers chosen from:
- 5-30 wt. % of at least one anionic vinyl monomer (A);
- 0-5 wt. %, of at least one vinyl monomer (B) having a secondary or tertiary amino group or a quaternary ammonium group;
- 70 to 95 wt. % of at least one non-ionic hydrophilic vinyl monomer (C);
- 0 to 2 wt. % of at least one polyfunctional vinyl monomer (F);
- 0-2 wt. % of at least one hydrophobic vinyl monomer (D);
- and
- 0-2 wt. % of at least one vinyl monomer (E) having at least one silicone group;
- wherein the sum of monomers (A) and (C) is 80 wt. % or greater, and the sum of monomers (A), (B), (C), (D), (E) and (F) is 100 wt. %.
